Twenty differently substituted 2,2′,2″,2‴ -[(2,2′-bipyridine-6,6′-diyl)bis(methylenenitrilo)]tetrakis(acetc acids) 75–94 were synthesized with the purpose of developing new markers to be used in bioaffinity assays based on the unique luminescence properties of EuIII and TbIII ions. The relative luminescence yields, excitation maxima, and emission decay constants were determined for the corresponding
合成了二十种不同取代的2,2',2'',2‴-[(2,2'-联吡啶-6,6'-二基)双(亚甲基腈)]四(乙酸)75-94,用于开发基于Eu III和Tb III离子独特的发光特性,用于生物亲和力测定的新标记。确定了相应的Eu III和Tb III螯合物的相对发光产率,激发最大值和发射衰减常数。在联吡啶基的取代基对发光性能的效果显著:最好相对发光率ř用于与给电子取代基的配体,获得(例如Me,Ph),吸电子取代基(例如NO 2,COOH)具有相反的作用。然而,在相对发光产率和取代基参数之间没有发现明显的相关性。
